Be it known that I, ELD'JH l). ANonRsoN, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful. Improvements in SpringWheels, of which the fOllOWiIlg is a specs fication.

The present invention relates to spring wheels and has for ,itsprincipal object to provide spring means between the tire or rim and thefelly of the wheel.

Another important object of the invention is ito provide means betweenthe felly and the rim for imparting the rotary motion of the former tothe latter said means being of a resilient nature.

A still further object of the invention to generally improve upon springwheels of this character by providing a device which will be extremelysimple in construction, reliable in operation, capable of beingmanufactured at a comparatively low cost, and well adapted to thepurpose for which it is designed.

In the drawing Figure 1 is a fragmentary elevation of a wheel embodyingmy invention, portions thereof being shown in section,

Figure 2. is a transverse section taken therethrough,

Figure 3 is a fragmentary longitudinal section through a portion of thewheel,

Figure 4c is a transverse section theretliroiigh taken substantially onthe line 4-4 of Figure 1 looking in the direction of the arrow,

Figure 5 is a detailed longitudinal section showing interior portions ofthe wheel in elevation, and

Figure 6 is a transverse section through the wheel, taken substantiallyon the line (i(% of liigure '1. looking in the direction of the arrow.

Referring to the drawing in detail it will be seen that a hub of anypreferred construction .1. provided with the conventional spokes 2extending therefrom and upon these spokes there is mounted a felly 3. AU- shaped annular plate 4: is mounted on the outer periphery of thefelly 3 and has circular plates 5 attached thereto and spaced therefromby the rings 6. These circular plates 5 are provided with recesses 7-for receiving suitable packing 8. A pair of c1r cular plates 9 areassociated with the plates 5 so as to engage their inner faces as isshown to advantage in Figure 4-. These inner plates 9 are attached tothe flanges of the rim. 10 which has mounted thereon a demountable rim11 of any preferred construction on which is carried a tire 12 eithersolid as shown or pneumatic or of any other preferred construction.

A plurality of curved substantially U- shaped springs 13 are disposedbetween the, rim l0 and the plate 4 attached to the felly These springshave their ends terminat ing in eye members for receiving the bolts '15which pass through the-flanges of the rim 10 and through. the -flangesof the plate 1 thus resiliently mounting the rim 10 in respect to thefelly 3. It will be seen that the plates 9 and 5 form a housing forthese springs and for other parts to be described hereinafter.

A plurality of boxes 16 are disposed beof each boxi16 and these flangesare riveted to the rim 10 in any suitable manner such is shown at 20.Inside of each box ad jacent the other end there is mounted a suitableresilient lining or member 21 for a purpose which will be evidenthereafter.

A plurality of plungers 22 radiate from thebase of the U-shaped plate 4being held in place by having their flanges 23 riveted thereto as at 24or in any other suitable manner. The outer ends of these plungers areslotted as at 25 for receiving the bolts 17 in the boxes 16. A pair ofsprings 27 is mounted on each of the bolts 17 one on each side of theplunger 22 situated adja centthereto. The springs 13 normally hold therim separated from the felly and thus the parts lwill be positionedsubstantially as is disclosed in Figure 1. VVheu the springs 13 arecompressed the outer end. of each plunger will move toward the outer endof its corresponding box and may even abut the resilient lining 21. Thesprings 27 take up any shock which will be caused by the movement of thefelly such as when the clutch is first let in upon an automobile andthus there would not be such a jar asthe machine was first propelledforwardly or rearwardly. This structure, of course, is

adapted to other vehicles and uses this pur tioular one merely beinggiven by ay of example.

It is to be understood that the present embodiment of the invention hasmerely been disclosed by Way of example and that numerous changes inform, material, and in i the combination and arrengement'of parts astween the telly and the rim, a plurality 01?. boxes attachedto the rim,plungers extending from the felly into the boxes, a bolt extendinglongitudinally of each of the boxes, said plungers being provided Withelongated slots for receiving said bolts, and spring elements disposedon each bolt one on each side of each plunger.

In testimony whereof I affix my signature in presence of two witnesses.
